Lack of galectin-3 alleviates trypanosomiasis-associated anemia of inflammation.

A typical pathological feature associated with experimental African trypanosomiasis (Trypanosoma brucei infection in mice) is anemia of chronic disease (ACD), which is due to a sustained type 1 cytokine-mediated inflammation and hyperactivation of M1 macrophages. Galectin-3 (Gal-3) was amply documented to contribute to the onset and persistence of type 1 inflammatory responses and we herein document that this protein is strongly upregulated during T. brucei infection.
